Definitions

  • the present invention relates to powered toothbrushes, and more particularly, to a toothbrush having a head with two distinct moving sections that each provide oral health benefits to the user.
  • Toothbrushes provide many oral hygiene benefits. For example, toothbrushes remove plaque and food debris to help avoid tooth decay and disease. They remove stained pellicle from the surface of each tooth to help whiten the teeth. Also, the bristles combined with the brushing motion massage the gingival tissue for stimulation and increased health of the tissue.
  • Powered toothbrushes have been available for some time. Powered toothbrushes have advantages over manual (non-powered) toothbrushes in that they impart movement to the bristles at much higher speeds than possible manually. They also may impart different types and directions of motion. These motions, generally in combination with manual movement of toothbrush by the user, provide superior cleaning than manual toothbrushes. Typically, powered toothbrushes are powered by disposable or rechargeable batteries that power an electric motor that in turn drives toothbrush head.
  • Known powered toothbrushes include a brush head with a bristle carrier portion that rotates, oscillates or vibrates in some manner so as to clean the teeth.
  • the bristles which typically comprise bristle tufts, are generally uniform with one end fixed into the bristle carrier portion and the other end free to contact the surface of the teeth while brushing.
  • the free ends of the various tufts present a surface envelope that is capable of some deformation when the bristles bend.
  • the bristles When in contact with the surface to be brushed, the bristles may deform so that the surface envelope tends to conform to the complex surface of the teeth.
  • Human teeth generally lie in a “C” shaped curve within the upper and lower jaw, and each row of teeth consequently has a convex outer curve and a concave inner curve. Individual teeth often have extremely complex surfaces, with areas that may be flat, concave, or convex. The more precise conformation between the bristles and the tooth surface, the more effective toothbrush may be in cleaning, whitening and/
  • Powered toothbrushes typically arrange the bristles in a compact conical or cylindrical pattern on a generally circular, disk-shaped bristle carrier.
  • the powered toothbrush heads are traditionally compact, generally oval in shape and heads are produced with a flat trimmed bristle pattern. Alternatively, other head shapes and bristle patterns are available.
  • a toothbrush 5 includes a handle portion 10 at a proximal end of toothbrush 5 and a head 11 at a distal end of toothbrush 5 .
  • Handle portion 10 has compartments for containing a powered motor 14 and batteries 15 and 16 .
  • Head 11 includes a generally circular bristle holder (carrier) 13 .
  • a rotatable shaft 12 extends from the motor 14 to head 11 .
  • a shaft coupling 17 may be located along the shaft 12 and configured to provide for the shaft 12 to be separated at a point between the motor 14 and head 11 . This permits the shaft to be removed from toothbrush 5 , e.g., for cleaning, servicing, or replacement.
  • Head 11 includes a post 18 that provides a rotational pivot axis for the bristle holder 13 containing bristle tufts 19 .
  • the distal end of the shaft 12 has a journal or offset 20 that is radially displaced from the longitudinal axis of the shaft 12 , which may be integrally formed therewith.
  • the bristle holder 13 has a slot 22 that receives the offset 20 .
  • the offset 20 and slot 22 are configured so as to be oriented toward the intersection of the shaft 12 axis and the longitudinal axis of the post 18 .
  • the motion of the offset 20 defines a circle about the shaft 12 axis and drivingly engages slot 22 such that the bristle holder 13 vibrates or oscillates about the post 18 axis through a rotational angle A.
  • the rotational angle A is defined by the displacement of the offset 20 from the shaft 12 axis relative to the diameter of the bristle holder 13 .
  • powered toothbrushes such as those described immediately above provide advantages over manual toothbrushes, they are subject to various limitations.
  • the bristles are placed in contact with the teeth during brushing, there is less bristle contact with adjacent areas, such as the gums.
  • adjacent areas such as the gums.
  • the unpowered bristle part floats separately from the powered bristle part. This necessitates separation or gaps between them. These gaps expose the internal workings of the head to foreign matter such as water, saliva, toothpaste, and food particles. This foreign matter may interfere with the workings of the unpowered bristle head.
  • the unpowered bristle part is spring-loaded to assist its resonance. Foreign matter may accumulate on or around the spring, interfering with its function. In addition, food particles may remain in the head and may fester and host microorganisms, which are undesirable if not potentially harmful when introduced directly into the mouth.
  • a powered toothbrush includes a handle portion at a proximal end and either a fixed head or a linkage for receiving a removable head at a distal end thereof.
  • a neck is further formed between the handle portion and the head.
  • the head includes two distinct movable parts that each and together provide oral health benefits, each being adapted to have a number of bristles or elastomeric cleaning members extending therefrom adapted to contact surfaces of one or more teeth and surrounding areas.
  • the powered toothbrush is further formed with a drive mechanism that imparts movement to the first movable part to deliver a cleaning, polishing, whitening action that supplements the cleaning efficiency of a typical powered toothbrush.
  • the first movable part in turn imparts movement to the second movable part.
  • the first movable head part is a first bristle carrier that supports a number of bristle tufts, elastomeric cleaning members, or a combination thereof.
  • the first bristle carrier is operatively mounted to the head and is coupled to the drive mechanism such that the first bristle carrier oscillates back and forth in a direction parallel to the toothbrush head.
  • the oscillating first bristle carrier is moved back and forth in a rotational direction.
  • the second movable part is in the form of a second carrier that is coupled to the head and includes an upstanding elastomeric element disposed along an upper surface thereof.
  • the elastomeric element has a first end that is coupled to the head and a second end that engages the first carrier so that the movement of the first carrier in the first direction is translated into movement of the elastomeric element in a second direction.
  • a single battery may be employed rather than the conventional two battery system.
  • the use of one battery allows for modification of the structure of the handle to be more user friendly.
